Purpose

This webpage/report is intended to aggregate information from different agencies (i.e. USACE, SFWMD, FWC, USGS and NOAA) into one spot to help inform local government agencies and stakeholders on conditions within Lake Okeechobee, the Caloosahatchee River and Estuary and Coastal southwest Florida. The data provided here should be considered preliminary and are subject to change.

Lake Flows: In the past 7 days the total outflow from Lake Okeechobee was 3,627 AF with 500 AF to the Caloosahatchee through S-77, 574 AF through S-310 in Clewiston, and 2,553 AF to the EAA through S-351, S-352, and S-354. The total net inflow to the Lake was 44,156 AF (42,145 AF from Fisheating Creek, S-71, S-72,S-84s, S-65EX, and S-65EX1) with a total backflow volume of 2,011 AF from C10A. Water conservation areas received flows of 6,710 AF, 11,482 AF, and 13,440 AF at WCA1, WCA2, and WCA3, respectively. Everglades National Park received 28,286 AF.
